M-SICP
(Multi-window Serial Interface Communication Protocol)
This document defines all the command and messages exchanged between the
Master (a PC or the other controller) and the Slave (the displays).
It also describes the ways to send or read the commands or the messages.
1. Protocol definition
M-SICP stands for “Multi-window Serial Interface Communication Protocol”.
The protocol is specifically designed to allow data communication in half duplex multi-point
environments, but it can also be used for half duplex point-to-point RS-232C communication.
2. Communication characteristics
A half duplex communication is implemented starting from the concept of a master-slave
structure, where the display is supposed to be the slave.
The first action is always taken by the master, which can be either a PC or any controlling device
(acting as server) interfaced to the monitor. After sending a command or a request in the
appropriate format the master receives from the slave an acknowledgement, which tells the
transmitter whether the command is not valid (or not executable, anyway) or it is accepted. In
case of a request, the requested information is sent back and it becomes the acknowledgement
by itself.

5. Transmission Formats
This is the format that the computer will send to the display to execute commands .
The format for this command transmission is as follows:
( total 13 byte )
-STX : Start of Text ( 0x0f )
-ID1 ~ ID3 : Set ID ( 001~100 )
-CM1 ~ CM3 : Command ( PWR, MIN, MUT,RML,KPL…… )
-R/W : Read/Write
-DA1 ~ DA3 : Data ( Values )
-IND : Index
-ETX : End of Text ( 0x0d )
6. OK Acknowledgement
The acknowledgement will be sent by the display to the computer to verify that the command has been
successfully received and executed. This format for this acknowledgement is as follows:
ex) <STX>001PWR#OFF#<ETX> ( Set ID : 1 , Power Off Acknowledgement )
ex) <STX>001PWRWOFF0<ETX> ( Set ID : 1 , Power Off Send )
7. Error Acknowledgement
The Error Values will be sent by the display to the computer to verify that the command has been
successfully received and executed.
This format for this Error Values is as follows:
ex) <STX>001PWRERROR<ETX> ( Set ID : 1 , Power Off Error )
STX ID1 ID2 ID3 CM1 CM2 CM3 R/W DA1 DA2 DA3 IND ETX
0x0f 0 0 1 P W R W O F F 0 0x0d
Hex ASCII (capital letter) Hex
STX ID1 ID2 ID3 CM1 CM2 CM3 R/W DA1 DA2 DA3 IND ETX
0x0f 0 0 1 P W R #O F F #0x0d
Hex ASCII (capital letter) Hex
STX ID1 ID2 ID3 CM1 CM2 CM3 R/W DA1 DA2 DA3 IND ETX
0x0f 0 0 1 P W R E R R O R 0x0d
Hex ASCII (capital letter) Hex
